Vacuum Furnace Graphite Parts for Heat Treatment

  • Good electrical & thermal conductivity.
  • High temperature resistance & wear resistance.
  • Excellent corrosion resistance & oxidization resistance.
  • Excellent machinability.
The vacuum furnace for heat treatment opens and shows its internal structure.

Vacuum furnace graphite parts are parts made of special graphite used in the heat treatment process, such as heating elements, protective shields, hearth plates, insulation layers, etc. As an important equipment in modern material processing industry, vacuum heat treatment furnaces are widely used in metal, ceramic, powder metallurgy and other fields.

As the heating and insulation furnace liner of vacuum furnace for heat treatment needs to work under vacuum and high temperature conditions, while graphite has the special property that its strength increases as the temperature rises. Besides, it is easy to machine, has high precision and low coefficient of linear expansion and can maintain its dimensional stability at high temperatures, making it the preferred material as the internal components in the vacuum furnace for heat treatment.

If you need high quality vacuum furnace graphite part solutions, we will provide you with professional technical support and service.

Application Introduction: About Heat Treatment and Vacuum Furnace Structure & Function

Heat treatment is a process of changing the physical and chemical properties of materials through heating and cooling. A vacuum furnace is a device in which heating and treatment can be performed in an oxygen-free or low-oxygen environment. In the heat treatment process, using a vacuum furnace can effectively reduce oxidation reactions, avoid the influence of the oxide layer on the material surface on material properties, and also protect material surface from contamination.

In a vacuum furnace for heat treatment, the heating zone is the key part for heating and treatment. This zone is mainly composed of heating elements (graphite rods and connecting pieces), insulation layers (graphite felt), and the hearth bottom (graphite holder). In the vacuum furnace, graphite heating elements are heated to high temperature and then transfer heat energy to the heated object through radiation, convection and conduction methods, thus making it achieve the desired temperature. This heating method has advantages of high efficiency, uniformity, and energy-saving, and can effectively improve the physical and chemical properties of materials.
